What is the difference between the Audi A2 FSI and Audi A2 TDI engines?

I am looking to buy an Audi A2 and I was wondering what the difference is between the FSI and TDI engines. Is there a significant performance difference? Do they have different maintenance needs?

The main difference between the Audi A2 FSI and TDI engines is the type of fuel they use. The FSI engine runs on petrol while the TDI engine runs on diesel. Depending on your driving habits and local fuel prices, one engine may be more cost-effective for you. Additionally, diesel engines typically have more torque and better fuel efficiency.
